Volumetric oil reservoir with pressure dropped from 2000 psi to 1000 psi with 30

Question

Volumetric oil reservoir with pressure dropped from 2000 psi to 1000 psi with 30 MM STB oil was produced. Gas oil ratio was 900 Scf/ STB at 1000 psi , while the current gas oil ratio is 2200 scf/STB . Porosity= 20% , Sw= 0.15 .the temperature of the reservoir is 160F. rsi =500 scf/STB , Boi = 1.3 bbl/STB, rs(1000 psia)= 300 scf/STB , Bo=1.20 bbl/STB 1. Calculate IOIP? 2. How much of Scf of involved gas remained in the reservoir at 1000 psi ? 3. Calculate gas saturation in the reservoir at 1000 psi ? 4. How much bbl of oil will be removed at 1000 psi if we re-inject of oil produced gas ? Volumetric oil reservoir with pressure dropped from 2000 psi to 1000 psi with 30 MM STB oil was produced.
